In all SpellForce games the main character is engaged in multiple battles. Not only does he fight for himself alongside some chosen companions, but also he has access to armies. Said armies are often made of different races and do have different units and ways of playing. See below which armies are available in each game.
- The Realm
- The Pact
- The Clan
- The Shaikan (since SpellForce 2: Dragon Storm)
- The Nameless (since SpellForce 2: Faith in Destiny)
These armies can be led into battle by Corporal Tahar.
